Abstract

The synthesis of T-8, T-10 and T-12 silsesquioxane cages from a range of starting materials: phenyl-cis-tetrol, 1,3-divinyltetraethoxydisiloxane and cyclopentyl T resins by using tetra n-butylammonium fluoride (TBAF) as the catalyst is described in this paper. The reaction yields obtained via the current route are better compared to those via the literature routes. Some of the cage compounds have been characterized by X-ray crystallography.
